SOFA CAPABLE OF BEING CONVERTED INTO A BED Filed Aug. 10, 1928 2 Sheets-Sheet 2 Patented July 14,

UNITED STATES MARIE LO UIS ADOLZPHE HENRI IDAUPHIN, (3F PARIS, FRANCE SOFA CAPABLE or BEING convnnrnn INTG A BED Application filed August 10, 1928, Serial No This invention has reference generally to improvements in that class of inventions known as furniture and more particularly relates to a sofa capableof being converted into a bed. i

A large number of systems have been devised for this purpose but they generally show the disadvantage of comprising a mechanism, which makes the installation impractical. Moreover, with these known systems of transformable sofas, the external appearance of a bed is maintained, this being detrimental to the elegance and presentability of these pieces of furniture. A similar inconveni5 ience is due to the fact, that in the devices of this kind as used at present, the convertible sofas are provided with a large number of wooden panels which at oncedisclose their use as beds.

The invention relates to a sofa, which can, by an exceedingly easy simple operation, be transformed into a normal bed for two persons. The transformation of this sofa into a bed can be effected by a single person without requiring any undue strain. No mechanism whatever is used for making this transformation which is carried out by simply causing the back of the sofa to rotate relatively to the seat. Finally, this piece of furniture comprises but two wooden panels which are laterally disposed and its external appearance is absolutely that of an ordinary sofa. The bed resulting from the extension of the piece of furniture is very comfortable and comprises a continuous mattress and bedstead.

The constitution and transformation of this sofa which is convertible into a bed will be hereinafter fully described with reference to the accompanying drawings in which:

Fig. 1 shows in front view the piece of furniture arranged as a sofa.

Fig. 2 is a side view corresponding to Fig. 1.

Fig. 3 is a back View of the sofa.

Fi 4 is a cross section made according to line X of the plan of Fig. 1 for the pur pose of showing the arrangement of the bedsteads and mattresses and the position they occupy respectively when the device is used 56 as a sofa.

. 298,860, and in France September 15, 1927.

Fig. 5 is a perspective view of the sofa. Fig. 6 is a side View of the sofa converted into a bed.

Fig. 7 is a transverse section corresponding to the preceding view. a

Fig. 8 is an half-section made according to the plan y2t of Fig. 5.

Referring now, more particularly, to the accompanying drawings in which similar reference characters designatecorresponding parts throughout the accompanying drawings there is provided an improved sofa-bed which consists of a stationary horizontal seat A and a back A connected for vertical swinging movement by means of the hinge 1 to the rear longitudinal edge of the seat and adapted to bearranged in a vertical position for use as a sofa or extended into a horizontal position aligning with the seat when the device is to be used as a bed. Two matresses B, B are also connected together along the seam line 2 and are disposed respectively on the seat A and the back A. Both the seat and the back may be lined with a suitable ornamental cloth or fabric. However, the upper face of the seat A and of the mattress B, as well as the internal face of the mattress B, which cannot be seen whenthe piece of furniture is used as a sofa, can be lined with an ordinary mattress or bedstead cloth. I

In Fig. 4: which shows diagrammatically the construction of the improved piece of furniture it will be seen that the seat A is used as a support for the mattresses B and B which, when folded down the one over the 5 other, form the seat of the sofa, the seat A of which constitutes the back.

The seat and back are provided laterally with two side panels, preferably of wood which are eachformed of two members C and C, the member C, being capable of laterally pivoting relatively to the member 0, through a rotary motion in the direction of the arrow 7, when it is desired to transform the sofa into a bed. This movability of the panel C is accomplished through very simple means, for example by providing an articulation axis at the lower rear angle of the two panel elements. .At its rear part, ate, the panelC is recessed to an extent corresponding to half and the panel members C have rectilinear vertical front edges, so that the shouldered or recessed edges 0 engage. the said front edges of member C to limit the forward movement of the latter when-the device is used as a sofa while the shoulders or recessed edges 0 overlie and contact with the upper or top edges of the panel member C when the devlce is used as a sofa.

When in the form of a sofa, the piece offurniture rests upon feet P which are conveniently secured to the bottom a of the seat. Fig. 1 shows the same, as well as Fig. 5, provided with a certain number of cushions D.

The interlocking of the members C and O of the lateral panel's is obtained in a very simple manner by means of a stop pin E which transverses the members C and C, a spring preferably returning constantly this pin to. its locking position.

In order to transform into a bed the sofa thus constituted, it is only necessary, after having released: the lateral stop pins E, to cause one of the panels C to rotate rearwardly and to. fold. the same down. This panel then drives the back forming bedstead A as well as the opposite panel C. After having proceeded to this folding down operatiomit is only necessary to extend the mattress B over the mattress B and to fold it down.

upon the bedstead A. The bedding then appears as sh-own in Fig. 7. Its length is that of a sofa. The bed thus formed is bounded at the head and at the feet by each one of the panels. In order to support the bed, auxiliary feet P are provided upon the rear face of the bedstead A. WVhen the piece of furniture is so arranged as to be used as a sofa, these feet are concealed in a suitable recess. When the back A is folded down, they fall outwardly or downwardly by virtue of their own weight and rest upon the floor.

In order to connect the rear edges of the bedsteads, there is provided a soft cloth F. The latter affords room in which, when the furniture is used as a sofa, it is possible to store the sheets, blankets and quilt adapted to constitute the bed. Fig. 7 shows that the latter absolutely constitutes an ordinary bed. for two people.

In order to ensure the strength of the piece of furniture, the hinge 1 for the articulation of the bedsteads will made of iron.

It may be mentioned that the weight of a preferably be sofa of this kind does not exceed 7 0 kgs. In order to transform the bed into a sofa, it is only necessary to lift the bedstead A and rotate the same in the direction opposite to the arrow 7; then, when every one of the panels 0 has come in front of the corresponding panel C, the springs of the locking pins E return the latter to their respective housings. The mattress B has been previously folded down over the other one.

A combined convertible sofa and bed comprising a stationary horizontal seat, a back connected for vertical swinging movement to the rear longitudinal edge of the seat and adapted to be arranged in a vertical position "for use 'asa sofa or extended into a horizontal position aligning with the seat when the device is to be used as a bed, side panels connected to both the stationary seat and to the back, the panels of the seat having rectilinear horizontal top edges and the pan els of the back having rectilinear vertical front edges, the panels on the seat being recessed on their inner surfaces to leave vertical shoulders engageable by the front edges of the panels on the back to limit the forward movement of the latter when the device is used as a sofa while the panels on the back are recessed on their outer surfaces to leave transverse shoulders which are adapted to overlie and contact with the upper edges of the seat panels when the device is used as a sofa, an operable connection between the adjacent panels on the back and on the seat to permit the back panels to follow the movement of the back during its displacements, means carried by the back and seat panels for releasably maintaining the back panels in an engaged position when the device is used as a sofa and permitting of a disengagement and displacement of the back section panels when the said back is extended to a horizontal position and means to support the back when in a horizontal position.

The foregoing specification of my sofa capable of being converted into a bed signed by me this 30 day of July, 1928.
